Detailed Description

Calculate the jet shape.

Calculate the differential and integral jet shapes in $P_{\perp}$ for a given set of jets. This particular jet shape projection calculates jet shapes relative to jet centroids, using only the particles associated to each jet, for the hardest $ n $ jets.

The rapidity scheme ( $ \eta $ or $ y $) has to be specified when invoking the constructor.

The differential jet shape around a given jet axis at distance interval $ r \pm \delta{r}/2 $ is defined as

\[ \rho(r) = \frac{1}{\delta r} \frac{1}{N_\mathrm{jets}} \sum_\mathrm{jets} \frac{P_\perp(r - \delta r/2, r+\delta r/2)}{p_\perp(0, R)} \]

with $ 0 \le r \le R $ and $ P_\perp(r_1, r_2) = \sum_{\in [r_1, r_2)} p_\perp $.

The integral jet shape around a given jet axes until distance $ r $ is defined as

\[ \Psi(r) = \frac{1}{N_\mathrm{jets}} \sum_\mathrm{jets} \frac{P_\perp(0, r)}{p_\perp(0, R)} \]

with $ 0 \le r \le R $ and $ P_\perp(r_1, r_2) = \sum_{\in [r_1, r_2)} p_\perp $.

The constructor expects also the binning in radius $ r $ to be supplied.

const PROJ& addProjection ( const PROJ &  proj,
const std::string &  name 
) [inline, protected, inherited]

Register a contained projection. The type of the argument is used to instantiate a new projection internally: this new object is applied to events rather than the argument object. Hence you are advised to only use locally-scoped Projection objects in your Projection and Analysis constructors, and to avoid polymorphism (e.g. handling ConcreteProjection via a pointer or reference to type Projection) since this will screw up the internal type management.
